I live on the Romeo / New Haven border, just south of me is 27 mile rd that is fed by the New Haven grid, Thankfully I am on the Romeo grid. My in-laws live on 27 mile and he had to instal a whole home generator. The big one that will take care of the entire house. When the power goes off, this thing kicks on automatically. Thier system goes down at least once every month. I have a 7000 watt portable generator hooked up to a by-pass panel with all the critical circuits (Well, Funace, sump, Fridge, a bank of plugs to run the TV). I had a licensed electrician come in and hook everything up. Best $200 I ever spent. The problem is the Aquarium is not connected to any of those circuits, so when the day arives I will be running a 100 ft extension cord to my den to run my aquariums.
Living out in the country has it's benifits, the well water is perfect for my aquariums, I'm just so very glad that I am north of 27 mile so I am not dealing with frequent power outages.
